Common Pitfalls

Last modified by Microchip on 2026/03/31 11:29

Overview

Analog-to-Digital Converters (ADCs) are critical components in modern electronic systems, but their performance can be compromised by several common pitfalls.

  • Sampling time
    • Sampling time is a frequent issue and can lead to inaccurate conversions if the input signal is not properly settled before sampling.
  • Crosstalk
    • Crosstalk can cause unwanted interference between channels and can further degrade signal integrity, especially in multi-channel ADCs
  • ADC input and data format
    • Selecting the wrong data format—such as using single-ended instead of differential inputs—can result in reduced noise immunity and measurement errors.
    • Address limitations
  • Signal-to-Noise Ratio (SNR) and Effective Number of Bits (ENOB)
    • Oversampling techniques are often employed, allowing for improved resolution and noise performance by averaging out random noise components.

Understanding and mitigating these pitfalls is essential for achieving accurate and reliable ADC measurements.
